MEANS FOR ATTACHIIATG HOOKS AND EYES T0 FETUS.

' for Attaching Hooks and Eyes to (Fabrics, of which the following is a specification, ref-' 7 erence being had'therein to the accompanyllil ing drawings. t

This invention has for its object the attachment of hooks and eyes to fabrics by fastening means applied to the hook-shank and spaced a art along the same suficiently to prevent twisting or displacement upon the garment when in use. Heretofore, difliculty has been encountered-in fastening the hooks in position by machine by reason of the in-, terference of the tongue overlying the greater portion of the length of the hook-shank and opposing a shleld against theapplic'ation of the primary fastening means initially in correct position.

According to the present improvement, the primary fastening means is applied to the hook-shank adjacent the eye at one end of the same adjacent the free end of thetongue, a relative shift being then efi'ected between the fabric and the hook to slide the initial fastening means along the hook-shank and beneath the tongue to the desired position, preferably at the bottom of the throat,

after which'a final fastening means is applied to the hook-shank within its lateral eyes. I j

In carrying out the invention, ll make use preferably of a sewing machinesuch as that of the United States Patent to J. J. Sullivan Not 777,564, of December 13, 1904, comprising stitch-forming mechanism including a rectilinearly reciprocating needle and a laterally jogging work-lgplder comprising a car rier sustalning a War -supporting plate and a superposed article-holding clamp sustained by an overhanging s ring-pressed arm bymeans of which anart icle, such as a flatbut ton, may be secured upon a fabric clamped beneath the same within the work-holder. According to the present improvement the article-holding clamp of the former construction is'replaced by a special form of clamp mounted upon the spring-pressed arm which is journaled in the present instance within a suitable bearing of a sllde-plate movably mounted upon the carrier ahdprb- Specification of Letters Patent.

of two difl'erent positions thereon, whereby Y the article-holdin means may be shifted relatively tothe woifii-supporting plate.

The article holder preferably comprises spaced aws formed with recesses in their lower faces at the adjacent edges-to receive and laterally position the eyed portion of the hook. A spring supportingiplate is op-' posed to said jaws above the' work-supporting plate and is formed at its outer end with a slot having a central stitch-supporting tongue and contracted adjacent the free end of said tongue to afiord lateral projections underlying said recesses for clamping the eyed portions of the hooks yieldingly within the latter.

The invention will be understood by reference to the accompanying drawings, in which Figure 1 is a rear side elevation of a sewing machine of'the well known Singer button sewer type fitted for handlinghooks and eyes in accordance with the present imarged perspective view of the work-handling means, with .a portion of the machine frame represented in dotted lines.

fabric and a garment hook applied thereto, and illustrating the fastening operation in its difi'erent stagesl The machine frame is constructed with the usual bed-plate 1 from which rises the overhanging bracket-arm 2 having 'journaled therein the main-shaft 3 to which is operatively connected the rectilinearly reciprocating needle-bar 4 carrying the needle 5 which constitutes one member of the stitchforming mechanism. Slidingly mounted upon the bed-plate 1 is the slide-bar 6 constitutin'fi a carrier for the work-holding parts. ising from one end of the slide-bar is a stud-pin 7 to which is adjustably so cured by the clamp-screw 8the block 9 fitted within a channel in the outer face of the crankarm '10 which is secured upon one ttt from the bed-plate. The rock-shaft 11 has upon its opposite end the crank-arm 13 carrying the roller-stud 13 entering a camgroove 14 in one face of the cam-wheel 15.

Throu h the described connections the camwheel is adaptedto impart endwise movements to the slide-bar, excepting when the block 9 is set at the neutral point in aline- -ment with the rock-shaft 11, as illustrated in Fig. 2, when the slide-bar is maintained against such endwise movement.

In its forward portion, the slide-bar 6 is secured to a block 16 extending through an aperture in the bed-plate and connected with the slide-plate 17 beneath the latter. The slide-plate 17 is connected b means of the link 18 with one arm 19 0 an anglelever fulcrumed upon the fixed stud-screw 20 and provided with a slotted arm 21 to which is adjustably attached one end of the link 22 having its opposite end connected by a universal joint to the lower arm 23 of a rock-lever fulcrumed at 24 upon the bracket 12 and having an upwardly extending arm 25 carrying the roller-stud 25 enterlng a cam-groove 26 in the rearward face ofthe cam-wheel 15. Through the connections thus described, the slide-bar or carrier derives from the cam-wheel lateral jogging movements.

The slide-bar or carrier 6 has rigidly secured upon its forward end the work-sup porting plate 27 adapted'to rest slidingly upon the usual throat-plate 28 applied to the bed-plate 1, and to sustain the fabric for reception of the articles to be attached thereto.

The bar 6 is vprovided intermediate its ends with a stud 29 entering an elongated J the stud-screw 43 upon which .is journaled aperture 30 in a slide-plate 31 resting upon said bar and confined thereon by means of the nut 32 applied to the stud 29. The slideplate 31 is ormed in its rearward end with a transverse groove or notch 33 affording a pivotalbearing for the rounded extremity of the downturned lip 34 of the clamp-arm 35 which is normally pressed downwardly toward the bar 6 by means of the flat spring 36 having a forked forward end embrac ing the stud 37 upon the clamp-arm and an apertured rearward end entered by the clamp-bolt 38 tapped into the block 39 chan-- neled in its upper face to receive the spring 36 and secured by suitable means upon the rearward portion of the slide-bar 6.

Secured .u on the bar 6 by means of the screw 40 an dowel-pin 41 is the stop-plate 42-. The plate 42 is formed in its under face with a segmental recess provided with the hub 44 of'a finger-lever 45 provided with an angularly extending hooked catcharm 46 which is adapted r engagement navoeee with a'lug 47 upon an adjustable plate 48 having an elongated aperture 48' to receive the shank of the fastening screw 49 by which it is adjustably secured to one edge of the slide-plate 31. The lug 47 not only affords a shoulder for engagement by the catch-arm 46 of the finger-lever but constitutes a projection upon the slide-plate 31 for en agement with the stop-plate 42 to limit t e forward movement of the slideplate.

The catch-arm is normally pressed into operative relation with the lug 47 by means of a spring 50 disposed within a recess 51 of the plate 42and connected at opposite ends respectively with the pin 52 upon the hub 44 and the fixed pin 53 within the recess 51, the catch-arm 46 and lug 47 being over the other in their approach to interlocking relation. The slide-plate is normally maintained retracted from the stopplate 42 by means of a spring 54 attached at one end to a stud-screw 55 depending from the clamp-arm 35 and at the opposite end to the transversely apertured upper end of the stud 29, the slide-plate being drawn backwardly by its described pivotal connection with the clamp-arm.

Pivotally mounted upon the lower face of the clamp-arm 35 by means of the studscrews 56 are the reciprocally movable clamp-levers 57 havin their forward portions downwardl ofiset to aiford workclamping jaws 5 and provided in their adjacent edges with the notches 58 and 59 to provide clearance for the trust of the needle in the production of the fastening stitches. These jaws are rabbeted at 60 in their lower faces adjacent the notches 59 and are provided with flaring recesses 61 adjacent the notches 58 for reception of the eyed portions of the hooks and eyes. The rabbeted parts 60 afford clearance for the body portion of the e es, the thread-eyes thereof being received y the recesses 61. ward of the rabbets 60 the jaws are beveled at 62 along their inner edges to provide ample clearance for the fastening stitches in the shift of the fabric relatively to the hook after the initial stitching operation.

, The enlarged outer portion of the clamparm 35 is formed with the usual longitudinal slot 63 to'receive the shanks of the screws 64 and 65 tapped into the slide-bar 66 provided with the forwardly extendin and downwardly ofiset stop-finger 67. o the under side of the bar 66 is secured the camplate 68 formed with the slightly convergent cam slots 69 entered respectively by the studs 70 depending from the clamp-levers 57, whereby the shiftin of the bar 66 effects the adjustment 0 the operative extremity of the stop-finger 67 and simul- Backtaneously adjust slightly the spacing apart post 71 having the cross-member 71', and

lid

of the article holding jaws to" accommodate garment hooks of different sizes.

The clamp-arm is provided wlth the usual tothis post is attached one end of the spring 72 whose opposite end is connected to the screwwhereby the latter is maintained ieldingly in contact with the stop-lever 3 fulcrumed upon the clamp-arm by, the screw-pin 74 and provided with the. segmental slotted cross-member 75 entered by the clamp-screw 76 by means of which it is adaptedfor adjustment in difl'erent positions for setting the article-holder for different sized hooks and eyes.

Secured upon the bottom of the clamps arm 35 bymeans'of the screw 55 is the foot of a spring-plate 77 having its forward endportion downwardly and forwardly offset to afiord a yielding support which is opposed to the bottoms of the article-holding jaws adapted for pressing the hook or eye within the recesses therein for a stitching operation. This plate is 'rovided in its forward end with a longitudinal slot '78 which is contracted at its forward end to' form the lateral extensions 79 underlyin the recessed and rabbeted edges of the jaws 57 and having extending from its inner end the central stitch-supporting tongue 80 which is slightly upwardly and forwardly inclined, as represented in Fig. 3 In the insertion of a hook within the holder, the

' shank is passed between the jaws 57' and dill above the tongue 80 into contact with the stop-finger 67, the lateral thread-eyes being received by the recesses 61, as represented in Fig. 6. The eyed portions of the hook are thus maintained seated and held frictionally within the recesses 61 by pressure of the spring-plate projections 7 9, the shank portion lying above the tongue 80.

The machine is provided with the usual clamp-operating rock-lever 81 fulcrumed .upon thebracket-arm and engaging at its forward end 'a collar 82 upon the lifting bar 83 j ournaled within the head of the bracketarm and provided at its lower end with a collar 84: having a backwardly extending arm 85 extendin article-holder may be raised and lowered in opposition to the spring 36 for introduction holder is raised, and a hook or eye inserted therein withits thread-eyes in register "with the outer needle clearance notches 58 of the jaws 57, after which the fabric is introbeneath the cross-member 71' of the post 1 by means ofwhich the fit duced beneath the same and the work-supporting plate 27 and the Work-holder is .of fabric m. The clamp-arm is then wholly or partially lifted and the fabric m shifted backwardly thereon whereby the fastening stitches s are slid along the hook-shank and beneath the tongue h, as represented in Fig. 9.-

The finger-lever 45 is now manually shifted to disengage the catch-arm 46 from the lug 47, whereby the article-holder is permitted to recede under the action of the s ring 54 to position the thread-eyes h" of the hook within the range of action of the needle, after which the machine is again operated to produce a second group of fastening stitches s, as represented in Figs. 6 and 10.

The function of the stitch supporting tplngue is to support the hook-shank when s 1 to prevent its getting under the stop-finger 67; and this tongue is bent upward slightly so as to prevent its catching in the fabric when the latter is shifted to move the initial fastening stitches beneath the tongue of the hook.

ting the fabric relatively thereto so as It is obvious that in the shifting of the garment hook or'eye within its holder from the catch-arm 46 with the lug l7, and by disengagement of the catch-arm from the lug 47 before the application of the final group of fastening stltches.

The article-holder as thus described is equally adapted for receiving either garment books or eyes, the only diderence in its mode of manipulation being the maintenance of the holder continuously in its final stitching position for handling eyes in order that the single group of fastening.

stitches will be applied through its threadeyes.
